2 Claims.

This invention relates to a supporting construction for a steam turbineand its condenser and it has for an object to provide apparatus of thischaracter wherein supporting is efiected in such a way that disturbancesof the running clearances of the turbine will occur to a minimum extent.

In the patent to Doran, No. 2,064,649, granted December 15, 1936, thereis disclosed and claimed a supporting construction for a turbine andcondenser wherein these parts are carried by side girders supported attheir ends; however, as the girders deflect and as they constitute partsof the side walls of the turbine, it will be obvious that the bladingcarried thereby may have its running clearances disturbed in relation tothe turbine rotor, that is, as the middle of each girder is deflecteddownward it carries with it the stationary blades of the turbine whichare attached to the side girders near the center of the span. Thebearings for supporting the turbine spindle and also carried by the sidegirders near the ends of the span are deflected downward a lesseramount.

In accordance with the present invention, the base or supportingconstruction is arranged so that deflection causes less difficulty andthe opportunity for disturbance of running clearances is correspondinglyreduced.

These and other objects are effected by the invention as will beapparent from the following description and claims taken in connection.with the accompanying drawing forming a part of this application, inwhich:

Fig. 1 is an isometric view showing a supporting construction made inaccordance with the present invention;

Fig. 2 is a sectional view taken along the line 11-11 of Fig. 1; and

Fig. 3 is a side elevational view of the supporting construction shownin relation to a turbine and a condenser supported thereby.

Referring now to the drawing more in detail, in Fig. 1, there is shown asupporting construction including side girders l0, l and inner girdersor structural members II, II, the ends of the inner girders H, II beingconnected by cross girders l2, 12. Vertical plates l3 extend outwardlyfrom the ends of the cross girders l2, I2 and are joined to the webs ofthe side girders H), II]. Also, sealing plates I4 (see Fig. 2) cover thespaces between each inner girder ll, side girder l0, and the verticalplates l3.

In use, the ends of the side girders ID are supported by any suitablemeans indicated generally at l5 and at l6, the upper part or cylindercover I! of the turbine is carried by the inner girders II, and thecondenser l8 has its inlet l9 suspended from the lower sides of the sidegirders l0 and the cross girders l2, the inlet of the condenser havingsealing relation with respect to the lower edges of the plates I3 andthe plates I4 being arranged to seal the spaces outwardly of the innergirders l l, inwardly of the side girders l0 and between the plates l3at either side of the turbine.

From the structure described, it will be apparent that, as the spanbetween supports, so far as the turbine is concerned, is considerablyshortened, the side girders ll being substantially the same length asthe turbine, and as such supports are freed of the additional weightimposed by the condenser, the latter being supported from the girders I0, bending and deflection resulting in disturbances of blade clearanceswill be considerably lessened.

While the invention has been shown in but one form, it will be obviousto those skilled in the art that it is not so limited, but issusceptible of various changes and modifications without departing fromthe spirit thereof, and it is desired, therefore, that only suchlimitations shall be placed thereupon as are specifically set forth inthe appended claims.

What is claimed is:

1. In a supporting construction for a turbine and its condenser, sidegirders, means for supporting the ends of the latter, a pair of innergirders forming a part of the turbine side walls, cross girdersconnected to the ends of the inner girders, vertical plates extendingfrom the cross girders and joined to the side girders, sealing platescovering the spaces disposed outwardly of the inner girders and inwardlyof the side girders and between said vertical plates, and a condenserhaving its inlet connected to the side and cross girders so as to besupported therefrom and having a sealed connected relation with respectto said vertical plates.

2. In a supporting construction for a turbine and its condenser, outerside girders; means for supporting the ends of the latter; a rectangularframe comprising side and cross girders; vertical plates for supportingthe corners of the rectangular frame from the side girders; a turbinecarried by the rectangular frame so that the side girders thereofconstitute portions of the side walls of the turbine; a condenser havingits inlet connected to the outer side girders and to the cross girdersof the rectangular frame so as to be supported thereby; and sealingplates for covering the spaces disposed outwardly of the side girders ofthe rectangular frame, inwardly of the outer side girders and betweencorner plates at either side of the rectangular frame.
